SPECIFICATION forming part of Letters Patent No. 408,245, dated August6, 1889. Application filed November 1, 1388. Serial No. 289,716. (Nomodel.)

To all whom it may concern:

Be it known that I, FRANCIS G. LILLY, a citizen of the United States,residing in Jamestown, in the county of Chautauqua and State of NewYork, have invented an Improvement in Petroleum-Burners; and I do herebydeclare that the following is a full and exact description of the same,reference being had to the accompanying drawings, making part of thisspecification.

My invention relates to retort-burners for petroleum and otherhydrocarbon fluids, being particularly adapted to burning crudepetroleum without clogging from the impurities of the fluid, andproducing clear flames and complete combustion.

In the accompanying drawings, Figure 1 represents a central verticalsection of a retort petroleum-burner constructed with my improvements;Fig. 2, a view of the under side of the same.

Like letters designate corresponding parts in both figures.

In the drawings, A represents the burnerretort; B, the feed-pipe throughwhich the petroleum is introduced into the retort from the reservoir orsource of supply, and C a valve by which the supply is out off and leton, and by which the quantity supplied to the retort is regulated.

From the interior of the retort a number of burnertubes D I) extenddownward to a suitable posit-ion beneath the retort and terminate,respectively, in ends a a, turned down around and then upward a littleway toward the retort. The inner upper ends I) b of these burner-tubesextend above the bottom 0 of the retort, so that, whatever the quantityof the petroleum fluid there may be in the retort at any time, it willnot reach the tops of the tubes, and consequently will not interferewith the discharge of pure vapor down the tubes as fast as generated inthe retort. All

the burner-tubes but one are or may be thus constructed and arranged.

One burner-tube E does not project above the bottom of the retort,inside of the same, although the part below and outside of the retort isor may be of the same form and construction as the other burner-tubes,the construction of the lower outside parts of the burner-tubes formingno essential part of my invention. By thus making the inner upper end ofthis one burner-tube even with or be-- low the inner surface of theretort-bottom any excess of the fluid in the retort may be dischargedthrough the said burner-tube, and it may be readily seen by thedischarge of fluid therefrom, if any, whether the petroleum is toorapidly admitted into the retort; but the special advantage of thisbur11er-tube,with the end flush with the retort-bottom, arises from thedischarge through the same of all residuum or impurities which may beformed or produced in the retort as fast as the same may collect there,so that the retort never be comes clogged nor its action interfered withby such impurities. This I have demonstrated by repeated trials and useof this burner; and thus a burner of exceedinglysimple and cheapconstruction is produced,which is adapted to the burning of crudepetroleum with complete freedom and regularity.

I claim as my invention In a petroleuni-burner, a vaporizingnetortprovided with outlet burner -tubes having their outlet-openings from theretort situated above the bottom of the retort, and oneoutletburnerrtube having its outlet-openiug from the retort flush withor below the bottom of the retort, substantially as set forth.

In witness whereof I have hereunto signed my name in the preset cc oftwo subscribing witnesses.

FRANCIS G. LILLY.
